Description

  The present invention relates to a shelf device in which a shelf board is mounted on a shelf board receiving member attached to a mounting member.

  BACKGROUND Conventionally, there has been known a shelf device in which a shelf board is mounted on the upper surface of a bracket (shelf plate receiving member) attached to a mounting member such as a column. For example, in the shelf device described in Patent Document 1, the shelf board clamp is attached to a slit provided in a column, and the shelf board is supported by sandwiching the shelf board with the bracket and the shelf board clamp. For example, in the shelf device described in Patent Document 2, a screw hole is provided on the upper surface of the bracket, and an engagement hole is provided at a position corresponding to the screw hole of the shelf board. And a shelf board is fixed with respect to a bracket by inserting a screw in an engagement hole and a screw hole.

Patent No. 5068984 JP 2002-345609 A

  According to the shelf support method described in Patent Document 1, it is possible to prevent the rear end side of the shelf from jumping. However, in this supporting method, the force for sandwiching the shelf acts in the vertical direction, which may be insufficient as a support for suppressing displacement of the shelf relative to the horizontal direction perpendicular to the vertical direction. .

  According to the shelf support method described in Patent Document 2, the shelf can be firmly fixed to the bracket. However, in this supporting method, since the screwing is performed on each of the left and right end portions of the shelf board, the shelf board can not be easily attached and removed.

  The present invention has been made to solve such problems, and it is an object of the present invention to provide a shelf device capable of easily removing and attaching a shelf board and reliably suppressing positional deviation of the shelf board. I assume.

  A shelf device according to the present invention includes a mounting member, a shelf board receiving member extending in the front-rear direction and attached to the mounting member, a shelf board mounted on the shelf board receiving member, and a shelf board supporting the shelf board A shelf member having a lower surface portion, an upper surface portion facing the lower surface portion, and a side surface portion connecting the upper surface portion and the lower surface portion; The shelf support member includes a support portion coupled to at least one of the mounting member and the shelf plate reception member, and an insertion portion formed on one end side of the support portion and inserted into the insertion portion. And.

  In the shelf device according to the present invention, the shelf board supporting member is connected to at least one of the mounting member and the shelf board receiving member at the supporting portion. Further, the insertion portion provided on one end side of the support portion is inserted into the insertion portion formed on the side surface portion of the shelf board mounted on the shelf board receiving member. Therefore, by inserting the insertion portion into the insertion portion, the shelf board can be supported by at least one of the mounting member and the shelf board receiving member via the shelf support member, and the insertion portion is pulled out from the insertion portion The support can be released at That is, the shelf board can be easily attached and detached by inserting and removing the insertion portion with respect to the insertion portion. In addition, while the shelf board can be easily attached and detached in this manner, vertical movement and horizontal movement (displacement) of the shelf board by the insertion part inserted into the insertion part of the side face part of the shelf board Can be reliably suppressed. By the above, while being able to perform attachment or detachment of a shelf board easily, position shift of a shelf board can be suppressed reliably.

  In the shelf device, the inserted portion may be provided on at least one of the side surfaces of the shelf plate along the front-rear direction. As a result, since at least the positional deviation of the shelf plate in the front-rear direction is more reliably suppressed by the insertion portion inserted into the insertion portion, the forward movement of the shelf plate can be effectively prevented.

  In the shelf device, the inserted portion may be provided on the side surface portion on the front side among the side surface portions of the shelf board. As a result, at least the positional deviation of the shelf in the lateral direction and the positional deviation in the forward direction are more reliably suppressed by the insertion portion inserted into the insertion portion, so the lateral deviation of the shelf and the forward direction Jumping can be effectively prevented.

  In the shelf device, the insertion portion may be formed so as to be inserted into the insertion portion and to restrict relative movement of the shelf plate relative to the insertion portion in the direction orthogonal to the insertion direction. . By inserting such an insertion portion into the insertion portion, the positional deviation of the shelf board with respect to at least one of the vertical direction and the horizontal direction orthogonal to the insertion direction is suppressed more effectively.

  ADVANTAGE OF THE INVENTION According to this invention, while being able to perform attachment or detachment of a shelf board easily, position shift of a shelf board can be suppressed reliably.

  Hereinafter, an embodiment of a shelf device according to the present invention will be described in detail with reference to the attached drawings. In the description of the drawings, the same elements will be denoted by the same reference symbols, without redundant description.

First Embodiment
FIG. 1 is a perspective view showing a shelf device 1 according to a first embodiment of the present invention. As shown in FIG. 1, the shelf device 1 includes a pair of mounting members 2 and 2, a pair of shelf board receiving members 3 and 3, a shelf board 4, and a shelf board supporting member 5. In the present embodiment, the front and rear direction is defined with the side where the mounting members 2 and 2 are positioned with respect to the shelf board 4 as the rear side. Further, the left-right direction is defined on the basis of a state as viewed from the front side to the rear side (that is, as viewed from the user of the shelf device 1).

  The pair of mounting members 2 and 2 are members for mounting the shelf board receiving members 3 and 3. The pair of mounting members 2 and 2 are provided at predetermined intervals in the left-right direction. The mounting member 2 is a quadrangular prism-shaped member extending in the vertical direction (vertical direction). The rear side surface of the mounting member 2 is fixed to, for example, an indoor wall surface (not shown) such as a house by a predetermined method such as screwing or bonding. On the side surface on the front side of the mounting member 2, a mounting portion 6 for mounting and fixing the shelf board receiving member 3 is formed. In the present embodiment, the mounting portion 6 is constituted by a plurality of slits 2 a for inserting and latching a locking portion (details will be described later) of the shelf board receiving member 3. A plurality of slits 2a are provided at equal intervals in the vertical direction so that the height position of the shelf board receiving member 3 can be adjusted at a plurality of positions. The mounting member 2 is not necessarily a columnar member extending in the vertical direction. For example, the mounting member 2 may be a columnar member attached to an indoor wall surface such as a house so as to extend in the lateral direction. In addition, the mounting member 2 is not necessarily a columnar member, and may be, for example, a flat member attached to a wall surface indoors.

  The pair of shelf board receiving members 3 and 3 are members that extend in the front-rear direction and are attached to the mounting members 2 and 2 respectively. The pair of shelf board receiving members 3 is attached to each of the pair of attachment members 2 so as to extend in the front-rear direction at the same height position. The shelf board receiving member 3 is a rod-like bracket having an L-shaped cross section extending in the front-rear direction in a state of being attached to the mounting member 2, and a side wall for reinforcing the shelf board receiving member 3 and attaching to the mounting member 2 A portion 3a and an upper wall portion 3b for mounting the shelf 4 are provided. Further, on the rear end side of the shelf board receiving member 3, two upper and lower two-step inverted L-shaped hooking portions (not shown) are formed. The shelf board receiving member 3 is fixed to the mounting member 2 by inserting the two hooks into the two slits 2a and 2a adjacent to each other in the vertical direction of the mounting member 2. However, the method of attaching the shelf board receiving member 3 to the mounting member 2 is not limited to the above-described method, and the shelf board receiving member 3 may be attached to the mounting member 2 by, for example, screwing.

  The side wall portion 3a extends in the vertical direction and extends in the front-rear direction, and extends so that the width in the vertical direction becomes constant over substantially the entire region in the front-rear direction. In the present embodiment, the region on the rear end side of the side wall portion 3a is wider than the region on the front end side so that the load of the shelf 4 can be sufficiently supported.

  The upper wall 3b extends horizontally inward from the upper edge of the side wall 3a in the left-right direction, and extends in the front-rear direction. On the front end side and the rear end side of the upper wall portion 3b, one convex portion 3c protruding upward is formed. The convex portion 3 c is formed corresponding to a groove 4 g provided in a shelf plate 4 described later. A through hole 3d for allowing the shelf board supporting member 5 to be described later to pass through is formed in the side wall portion 3a of the left shelf board receiving member 3 (details will be described later). The upper wall 3b does not necessarily extend horizontally from the upper edge of the side wall 3a inward in the left-right direction, but may extend horizontally in both the inner and outer sides in the left-right direction. . Further, in the present embodiment, the configuration having the convex portion 3 c for performing displacement suppression and alignment of the shelf board 4 more efficiently and suitably is illustrated, but even if the configuration does not have the convex portion 3 c Good. In the present embodiment, a configuration in which the shelf board supporting member 5 is connected only to the left shelf board receiving member 3 among the pair of left and right shelf board receiving members 3 and 3 will be described. Similar to the left shelf board receiving member 3, the shelf board supporting member 5 may be connected.

  The shelf board 4 is a rectangular plate-like member placed on the upper wall portions 3b and 3b of the pair of left and right shelf board receiving members 3 and 3. The shelf 4 has a lower surface 4a, an upper surface 4b facing the lower surface 4a, and side surfaces 4c, 4d, 4e, 4f connecting the lower surface 4a and the upper surface 4b. The side surface 4c is a side surface along the front-rear direction located on the left side of the shelf board 4, the side surface 4d is a side surface along the front-back direction located on the right side of the shelf board 4, and the side surface 4e is The side surface portion 4 f is a side surface portion located on the front side of the shelf board 4, which is a side surface portion located on the front side of the shelf board 4. The lower surface portion 4a, the upper surface portion 4b and the side surface portion 4f are smoothly connected in a rounded manner. Grooves 4g, 4g corresponding to the projections 3c, 3c of the shelf board receiving member 3 described above extend in the left-right direction on the front end side and the rear end side of the lower surface portion 4a. By the convex portions 3c, 3c being fitted in the groove portions 4g, 4g, the positional deviation of the shelf board 4 in the front-rear direction is suppressed. A plurality (five in the drawing) of the insertion portions 10 extending inside the shelf plate 4 are formed in the side surface portion 4 c at equal intervals in the front-rear direction. However, at least one insertion portion 10 for inserting an insertion portion 11 described later may be formed, and a plurality of insertion portions may not be formed. The insertion portion 10 may extend in the longitudinal direction of the shelf 4 (the left-right direction in the present embodiment) and penetrate to the right side surface 4 d of the shelf 4. The material of the shelf 4 is not particularly limited, and may be metal, resin, or wood. Among them, the resin-made shelf board 4 can be preferably used because it is easy to handle. In particular, for the purpose of weight reduction etc., the shelf board 4 made of resin having a hole in the side surface 4c by thinning or the like can use the hole as the insertion portion 10, and the processing of the insertion portion 10 is unnecessary. Can be preferably used.

  Next, the configuration of the shelf board support member 5 will be described in detail with reference to FIGS. 1 and 2. FIGS. 2A and 2B are diagrams schematically showing a part of the shelf device 1 when the shelf device 1 is viewed from the front side. FIG. 2A is a schematic view showing a state in which the shelf board 4 is not supported by the shelf board support member 5. FIG. 2 (b) is a schematic view showing a state in which the shelf 4 is supported by the shelf support member 5. Further, FIG. 1 shows a state in which the shelf 4 is not supported by the shelf support member 5. In the following description, unless otherwise stated, the shelf board supporting member 5 in the state of being connected to the shelf board receiving member 3 (the state shown in FIGS. 1 and 2) will be described. The shelf board supporting member 5 is a member for supporting the shelf board 4 and suppressing movement (displacement) of the shelf board 4 in the vertical direction and the horizontal direction. The shelf board support member 5 has an insertion portion 11, a support portion 12, and a detachment prevention member 13. The insertion portion 11 is connected to one end 12 a of the support 12, and the detachment prevention member 13 is connected to the other end 12 b of the support 12.

  The support portion 12 is a long plate-like (plate) member bent in a U-shape in two steps from the one end 12a side to the other end 12b side. When the support portion 12 is a plate-like member, the vertical direction of the shelf board support member 5 is easily stabilized, but the support portion 12 may be a rod-like member or the like. The support portion 12 includes an upper side piece 16 extending in the left and right direction on the upper side, a lower side piece 17 extending in the left and right direction on the lower side, and an upper side piece 16 and a lower side piece 17 extending in the vertical direction. And a connection piece 18 for connecting the The upper side portion 16 is provided at a height position corresponding to the side surface 4c (and the inserted portion 10) of the shelf board 4 and is provided at the end on the side surface 4c side (that is, the inner end in the left-right direction). An insertion portion 11 is provided. The end corresponds to one end 12 a of the support 12. The lower side piece portion 17 is provided at a height position corresponding to the side wall portion 3a (and the through hole 3d) of the shelf plate receiving member 3 of the shelf plate 4, and is inserted into the through hole 3d. A detachment preventing member 13 is provided at the end on the receiving member 3 side (that is, the inner end in the left-right direction). The end corresponds to the other end 12 b of the support 12. The support portion 12 is connected to the shelf board receiving member 3 via the through hole 3 d so as to slide in the left and right direction. The connection piece 18 is connected to the end of the upper side piece 16 and the lower side piece 17 on the outer side (the side opposite to the shelf 4) in the left-right direction. In FIG. 2B, the shelf 4 is supported in a state where the connection piece 18 and the side surface 4c of the shelf 4 are separated, but the shelf from the side surface 4c of the shelf 4 is used. In order to reduce the protrusion of the plate support member 5 or to more effectively suppress the movement of the shelf 4 in the left-right direction, the upper side of the connection piece 18 and the side surface 4 c of the shelf 4 are in contact. The shelf board 4 may be supported in a state in which the piece portion 16 is stored in the inserted portion 10. Further, the upper side piece portion 16 may be omitted, and a configuration in which the insertion portion 11 is provided at the upper end portion of the connection piece portion 18 may be adopted. In this case, the upper end of the connection piece 18 corresponds to the one end 12 a of the support 12. In these cases, contact is made with the connection piece 18 of the side 4c of the shelf 4 so that the side 4c of the shelf 4 and the side of the connection piece 18 fall within the same plane (they become flush). A notch or the like may be provided in the portion.

  In order to prevent the support 12 from coming out of the through hole 3 d when the shelf board support member 5 is slid to the outside (here, the left side) in the left-right direction, the detachment prevention member 13 is It is a member connected to the other end 12b side. The detachment preventing member 13 has an outer shape larger than at least the lower side piece 17 and the through hole 3 d when viewed from the left and right direction. A state in which the insertion portion 11 is inserted into the insertion portion 10 so that the support portion 12 can be slid to such an extent that the mounting operation of the shelf 4 can be performed by removing the insertion portion 11 from the insertion portion 10 (FIG. In the state b), the detachment prevention member 13 is disposed at a position spaced apart from the side wall portion 3a of the shelf board reception member 3 in the left and right direction (here, right side). The detachment prevention member 13 may be integrally formed with the support portion 12 or may be formed as a separate member.

  The insertion portion 11 is a member to be inserted into the inserted portion 10 formed on the side surface portion 4 c of the shelf 4. The insertion portion 11 is configured to be able to be accommodated in the inserted portion 10 by projecting from the one end 12 a of the support portion 12 toward the side surface 4 c of the shelf 4. Here, in the present embodiment, the insertion portion 10 is configured by a hole formed in the side surface 4 c, and has an inner surface portion that surrounds the entire insertion portion 11 inserted. Here, the insertion portion 10 is constituted by a rectangular hole, and the inner surface portions 10a and 10b opposed to the insertion portion 11 in the horizontal direction (forward and backward) and the inner surface portion 10c opposed to the lower portion , And an inner surface portion 10d opposed to the upper side. Therefore, when the shelf board 4 is moved relative to the shelf board support member 5 in the direction (vertical direction or horizontal direction in the present embodiment) orthogonal to the insertion direction (the left and right direction in the present embodiment) By moving the shelf board 4 in contact with the inner surface portions 10a, 10b, 10c, and 10d of the insertion portion 10 to support the shelf board 4), the movement of the shelf board 4 can be suppressed.

  In addition, since the lower part of the shelf 4 is supported by the shelf receiving member 3, in the inner surface of the inserted portion 10, the inner surface 10d opposed to the insertion portion 11 at the upper side may be omitted. The insertion part 10 should just have inner surface part 10a, 10b which opposes at least horizontally, and the inner surface part 10c which opposes below. That is, the upper surface portion 4b of the shelf 4 may be partially cut away at a position corresponding to the insertion portion 10, and the insertion portion 10 may be opened upward. Further, the inner surface of the insertion portion 10 does not have to be a flat surface, and the inner surface may be a curved surface by the insertion portion 10 being configured by a circular or elliptical hole or the like.

  Moreover, the insertion part 11 may be inserted in the to-be-inserted part 10, and may be formed so that the relative movement with respect to the shelf board supporting member 5 of the shelf 4 in the direction orthogonal to the insertion direction can be controlled. When restricting relative movement of the shelf board 4 with respect to the shelf board support member 5 in the horizontal direction (here, the front-rear direction), the insertion portion 11 is inserted in the insertion portion 10 into the insertion portion 10. While being in contact with the inner surface portion 10a at least in part, it is in contact with at least a portion of the inner surface portion 10b of the inserted portion 10. Thus, when the insertion portion 11 is inserted into the insertion portion 10, the insertion portion 11 is formed so that the operation of shaking the shelf plate 4 in the horizontal direction (front-rear direction) relative to the shelf plate support member 5 can be suppressed. ing. In order to form such an insertion portion 11, for example, the width of the insertion portion 11 in the front-rear direction (the outermost side in the front-rear direction) than the dimension between the inner surface 10a and the inner surface 10b of the insertion portion 10 It may be formed as an elastic member having a large width in the portion where it is located. In this case, the insertion portion 11 presses the inner surface portions 10a and 10b of the insertion portion 10 by being pushed into and inserted into the insertion portion 10, so that the insertion portion 11 is against the inner wall surface of the insertion portion 10 It will be fixed firmly. Therefore, it can be expected that not only the movement of the shelf 4 in the horizontal direction can be restricted but also the movement of the shelf 4 in the vertical direction can be restricted. Also, for example, the shelf support member 5 of the shelf 4 can be formed by forming the width in the front-rear direction of the insertion portion 11 to be the same as or substantially the same as the dimension between the inner surface portion 10a and the inner surface portion 10b. The insertion part 11 which can regulate relative movement to it can be formed. At this time, the insertion portion 11 may be made of a rigid material instead of an elastic material. When restricting relative movement of the shelf board 4 to the shelf board supporting member 5 in the vertical direction, the insertion portion 11 and the inner surface portion 10c of the insertion portion 10 in a state of being inserted into the insertion portion 10 It abuts on at least one part, and abuts on at least one part the inner surface 10d of the inserted portion 10. A specific configuration may adopt a structure having the same effect as the structure when in contact with the above-described inner surface portions 10a and 10b. The movement of the shelf board 4 may be restricted in both the horizontal direction and the vertical direction by bringing the insertion portion 11 into contact with the inner surface portions 10a, 10b, 10c and 10d.

  Next, the mechanism which supports the shelf 4 by the shelf support member 5 is demonstrated using FIG. In the state shown in FIG. 2B, when the operator slides the shelf board supporting member 5 in the direction in which the insertion portion 11 is pulled out from the insertion portion 10 (left direction in this embodiment), FIG. It will be in the state shown in. By this, the shelf board 4 can be easily removed. In the state shown in FIG. 2A, when the operator slides the shelf support member 5 in the direction of inserting the insertion portion 11 into the insertion portion 10 (insertion direction; right direction in the present embodiment), FIG. It will be in the state shown to 2 (b). Thereby, the shelf board 4 can be easily supported.

  In the state shown in FIG. 2 (b), when the shelf 4 moves in the forward or backward direction (or when moving), the insertion portion 11 abuts on the inner surface portion 10a or the inner surface portion 10b. , Receives a load from the inner surface 10a or the inner surface 10b. The load received by the insertion portion 11 is received by the shelf board receiving member 3 via the support portion 12. Thus, the movement of the shelf 4 in the front-rear direction is suppressed. In addition, when the shelf 4 moves upward or downward (or tries to move), the insertion portion 11 abuts on the inner surface portion 10d or the inner surface portion 10c, and from the inner surface portion 10d or the inner surface portion 10c Receive a load of The load received by the insertion portion 11 is received by the shelf board receiving member 3 via the support portion 12. Thereby, the movement of the shelf 4 in the vertical direction is suppressed. Further, the movement of the shelf board 4 in the outward direction (left direction in the present embodiment) is suppressed by the interference of the detachment prevention member 13. That is, when the shelf 4 moves outward more than a certain amount, the detachment prevention member 13 abuts on the side wall portion 3 a of the shelf receiving member 3 to be a support, whereby the further movement of the shelf 4 outward is caused. Is suppressed. In addition, the movement of the shelf board 4 in the inward direction (the right direction in the present embodiment) is suppressed by the interference of the connection piece portions 18. That is, when the shelf 4 is moved inward by a certain amount or more, the inner side surface portion (here, the right side surface portion) of the connection piece 18 abuts against the side surface portion 4c of the shelf plate 4 to be a support. Inward movement of the shelf board 4 is suppressed. In addition, by forming the through hole 3 d a little larger than the lower side piece 17 of the support portion 12, there may be a slight gap between the through hole 3 d and the lower side piece 17, Even in such a case, the range of positional deviation of the shelf 4 can be limited within a certain range.

  Next, the operation and effects of the shelf device 1 according to the present embodiment will be described. In the shelf device 1 according to the present embodiment, the shelf board support member 5 is connected to the shelf board receiving member 3 via the through hole 3 d in the support portion 12. Further, the insertion portion 11 provided on the side of the one end 12 a of the support 12 is inserted into the inserted portion 10 formed on the side surface 4 c of the shelf 4 placed on the shelf receiving member 3. Therefore, by inserting the insertion portion 11 into the insertion portion 10, the shelf board 4 can be supported by the shelf plate receiving member 3 via the shelf support member 5, and the insertion portion 11 is pulled out from the insertion portion 10 Support can be released. That is, the shelf board 4 can be easily attached and detached by inserting and removing the insertion portion 11 with respect to the insertion portion 10. Moreover, while the shelf board 4 can be easily attached and detached in this manner, the vertical direction and the horizontal direction of the shelf board 4 can be obtained by the insertion portion 11 inserted into the insertion portion 10 of the side surface 4 c of the shelf board 4 Movement (displacement) can be reliably suppressed. By the above, while being able to perform attachment or detachment of shelf board 4 easily, position shift of shelf board 4 can be controlled certainly. Further, in the shelf device 1, the shelf board 4 is not supported (fixed) on the mounting member 2, the shelf board receiving member 3 or the like by using a bracket, a screw or the like exposed on the top surface 4b side of the shelf board 4. Therefore, a metal fitting, a screw, etc. are not exposed to the upper surface part 4b side, and the range which can be used as a shelf is not restrict | limited. Moreover, the feeling of use of the shelf board 4 is not impaired.

  Further, in the shelf device 1 according to the present embodiment, the inserted portion 10 is provided in at least one of the side surfaces along the longitudinal direction among the side surfaces of the shelf 4 (in the present embodiment, the side surface 4 c). The shelf board supporting member 5 is connected to the shelf board receiving member 3 through the through hole 3d. Thereby, since the positional offset with respect to the front-back direction of the shelf board 4 is suppressed more reliably by the insertion part 11 inserted in the to-be-inserted part 10, jump-out to the front of the shelf board 4 can be prevented effectively. . In addition, jumping of the shelf board 4 upward can be effectively prevented.

  Next, first to fourth modified examples of the shelf board supporting member 5 in the shelf device 1 will be described with reference to FIG. 3 (a) to 3 (d) show the shelf device 1 including the shelf board support members 20, 30, 40, and 50 according to the first to fourth modifications as the shelf board support member 5 as viewed from the front side. It is the figure which showed typically a part of shelf apparatus 1 in the case where it carried out. In the description of the shelf board supporting members 20, 30, 40, and 50 according to the following modified examples, the description of the same components as the shelf board supporting member 5 will be largely omitted. The same reference numerals as the reference numerals of the parts of the shelf support member 5 are given to the parts of the shelf support members 20, 30, 40, 50 which are largely the same as the parts of the shelf support member 5.

  A shelf board supporting member 20 according to a first modification shown in FIG. 3A is mainly composed of the shelf board supporting member 5 and the main supporting plate 5 in that a part of the lower side piece is a spring member (elastic member) 21. It is different. Specifically, in the shelf board supporting member 20, the lower side piece is connected to the spring member 21, the first lower side piece 22a connected to the left end of the spring member 21, and the right end of the spring member 21. It is formed of the 2nd lower piece part 22b. However, the left end of the spring member 21 may be directly connected to the lower end of the connection piece 18. In this case, the first lower side piece 22a does not exist, and the lower side piece is formed by the spring member 21 and the second lower side piece 22b. Further, the right end of the spring member 21 may be directly connected to the detachment prevention member 13. In this case, the second lower side piece 22b does not exist, and the lower side piece is formed by the spring member 21 and the first lower side piece 21a. When the insertion portion 11 is pulled in a direction out of the insertion portion 10, the insertion portion 11 is pulled back in the direction of being inserted into the insertion portion 10 by the elastic force of the spring member 21. For example, the detachment preventing member 13 and the shelf board receiving member 3 are in close proximity, and when pulling out the shelf board supporting member 20 to the left, the detachment preventing member 13 is hooked on the side wall portion 3 a of the shelf board receiving member 3 ing. Alternatively, the portion closer to the detachment prevention member 13 than the spring member 21 (here, the second lower side piece 22b or the detachment prevention member 13) is a shelf board by a predetermined method (for example, screw attachment or attachment by attachment) It may be supported relative to the receiving member 3. Further, the length of the spring member 21 is adjusted so as to be in a normal state (state in which the elastic force does not work) when the insertion portion 11 is inserted into the insertion portion 10.

  According to the shelf board support member 20, the elastic force of the spring member 21 can prevent the insertion portion 11 from being detached from the insertion portion 10. Therefore, vertical movement or horizontal movement (displacement) of the shelf 4 is more reliably suppressed. In addition, when supporting the shelf 4 by the shelf support member 20, the operator pulls the connection piece 18 by hand in the left direction, for example, and places the shelf 4 on the shelf receiving member 3. It only needs to release the hand from the connection piece 18. In this way, the insertion portion 11 is automatically inserted into the insertion portion 10 by the elastic force of the spring member 21. Therefore, the mounting operation of the shelf 4 can be easily performed.
